DAVIE – Seven months after he had no one running deep, after his pop-gun offense couldn't create a quick touchdown, Ryan Tannehill stood in the first huddle of the new year and called the play this off-season was meant to solve.

"The long ball,'' as Tannehill said later.

"I figured it coming to me," receiver Mike Wallace said.

So, right from the start, you got a glimpse into the most important issue of this Dolphins summer.

...

You can crunch the unforgiving numbers to see this. Tannehill completed only four of 17 passes thrown more than 30 yards last year in an NFL era built around such passes. That was the lowest number of the 31 quarterbacks who played at least 10 games.

That was the major problem in why the Dolphins ranked 27th in scoring offense last year. It's why the receiving corps was overhauled. ...
